Effective working principle: The lumbar traction bed uses a rack-and-pinion mechanism that converts the natural elastic force of the muscles into effective traction therapy. Recommended traction duration: For best results, use 20-30 minute sessions, no more than twice per day, to relieve tension and discomfort in the neck and lower back. Versatile functionality: Designed for both neck and lumbar traction with adjustable angles for targeted relief, addressing conditions such as cervical spondylosis, lower back pain, herniated discs, and sciatica. Universal fit and safety: Suitable for users weighing less than 90 kg and shorter than 180 cm, with a traction capacity of 0-800 N. To prevent adverse effects, avoid excessive traction. Use scenarios: - After long periods of desk work, to relieve neck stiffness and shoulder tension. - Regular lumbar traction to help manage chronic lower back pain. - Part of a treatment plan for sciatic or disc-related symptoms, under professional guidance.
